Implement testing JSON RPC APIs for retesteth

[cburgdorf]

What is wrong?

At the Ethereum Client Developer Conference @winsvega gave a quick overview about retesteth which aims to become the new standard for testing the different ethereum clients.

Here's a bit of background copied from the projects readme:

• A testtool that would be capable of running current StateTests + Blockchain tests against any client by sending rpc request to the client instatnce on either local or remote host.
• Filling existing tests (generating post state from *Filler.json instruction files) using rpc and any exisiting client
• Running rpc request - response tests with a provided client on localhost
• Bunch tests execution with many clients with many threads
• A minimum set of additional rpc methods for client to negotiate with the tool: testeth via RPC requirements retesteth#5

Currently ethereum-cpp has spearheaded the proof of concept phase for retesteth and @winsvega is looking for other client teams to adopt the testing APIs to be able to get tested through retesteth.

How can it be fixed

A good overview of the expected testing APIs can be found here: ethereum/retesteth#5

For anyone aiming to tackle this, it would probably be a good idea to connect with @winsvega and just quickly discuss how to get startet.

I'd push for this to be a high-ish priority.
